A nurse is providing dietary teaching to a client who has a prescription for tranylcypromine. The nurse should instruct the client to avoid which of the following foods while taking this medication?

Choice A reason: Fresh salmon is safe to consume while taking tranylcypromine. It does not contain high levels of tyramine, which is the substance that interacts dangerously with monoamine oxidase inhibitors (MAOIs) like tranylcypromine. Choice B reason: Aged cheese is the correct answer because it contains high levels of tyramine. When combined with MAOIs, tyramine can precipitate a hypertensive crisis, which is life-threatening. This is why aged cheese and other tyramine-rich foods must be strictly avoided. Choice C reason: Smoked meats also contain tyramine, but aged cheese is the most classic and well-documented food to avoid. Smoked meats are risky, but the priority teaching point is aged cheese. Choice D reason: Red wine contains tyramine and can also interact with MAOIs, but again, aged cheese is the most direct and classic food to highlight in teaching.
